3. C: Vertical Distance Target Group,
This target group includes 19 strings, with the adjacent string interval is 10mm.
4. D: Horizontal Distance Target Group,
This target group includes 7 strings, with adjacent string interval is 20mm.
5. E: Hyperechoic(tumor-like) Target,
Hyperechoic target(tumor-like), is located between 70-80 mm in depth, with a 10 mm diameter
cylindrical shape. The cylinder axis is parallel to the target string.
6. F: Anechoic (Cyst-like, 10 mm in diameter) and stones-like Target,
Cyst-like cylindrical shape target, is located between 70-80 mm in depth, with 10 mm in diameter of
the cylinder. The axial is parallel to the target string. Stones mimicking target is located in the center
of the cyst target with irregular shape, among which the maximum size is of about 4-6 mm.
7. G: Anechoic (Cyst-like, 6 mm in diameter) Target,
Anechoic (cyst-like) target, is located between 47-53mm in depth, with a 6mm diameter cylindrical
shape. Its cylinder axis is parallel to the target string.

The detail introduction of 14 target groups is as following:
1. A1-A4: Axial Resolution Target String Group,
The top strings of each target group are at the depth of 10mm, 30mm, 50mm, 70mm. The vertical
distances between adjacent strings in each target group are 3mm, 2mm, 1mm, 0.5mm respectively.
The horizontal distances between adjacent are 1mm.
